==History== The reaction between phenol and aldehyde was first reported in 1872 by [[Adolf von Baeyer]], though its use as a commercial product was not considered at the time.<ref>{{cite web | url=https://www.chemistry-online.com/organic-chemistry/named-reactions/bakelite-process/ | title=β· Bakelite process | date=February 14, 2023 }}</ref> [[Leo Baekeland]] was already wealthy due to his invention of Velox [[photographic paper]] when he began to investigate the reactions of [[phenol]] and [[formaldehyde]] in his home laboratory. Chemists had begun to recognize that many natural resins and fibers were [[polymer]]s.{{Source?|date=December 2024|reason=way too early}} Baekeland's initial intent was to find a replacement for [[shellac]], a material in limited supply because it was made naturally from the secretion of [[lac insect]]s (specifically ''[[Kerria lacca]]''). He produced a soluble phenol-formaldehyde shellac called [[Novolak]], but it was not a market success,<ref name="Landmark"/> even though it is still used to this day{{cn|date=March 2025}} (e.g., as a [[photoresist]]). He then began experimenting on strengthening wood by impregnating it with a synthetic resin rather than coating it.<ref name="Landmark"/> By controlling the pressure and temperature applied to phenol and formaldehyde, he produced a hard moldable material that he named Bakelite, after himself<ref name="time" >{{cite magazine | last = Amato | first = Ivan | title = Leo Baekeland | magazine = [[Time (magazine)|Time]] | date = March 29, 1999 | url = http://www.time.com/time/time100/scientist/profile/baekeland.html | archive-url = https://web.archive.org/web/20000407201944/http://www.time.com/time/time100/scientist/profile/baekeland.html | url-status = dead | archive-date = April 7, 2000 }}</ref><ref name="History">{{cite web | title = Leo Baekeland | work = Plastics | date = June 28, 2000 | url = http://www.historylearningsite.co.uk/plastic.htm }}</ref> and the heat curing process it required.

By 1910, Baekeland was producing enough material in the US to justify expansion.
